Thanks for taking a shot at it
No relays on the side of the tranny. That's where the NSS is located, left side.
Check for a short to GND.
- Neutral Safety Switch (NSS) may be shorted. Check switch with connector removed. Center pin should be grounded only while in PARK or NEUTRAL. Outer pins should have continuity only in REVERSE, never shorted to ground.
- Neutral Safety Switch wiring may be shorted. Check for damaged/shorted wires at/near NSS.
Location shown in diagram, inexpensive part, easy to replace.
